TO THE METHOD OF CALCULATION OF THE WINTER MODE OF THE LOWER REACH OF THE SYR-DARYA RIVER

In the article various methods of calculation of the winter drain, based on use of supervision over water levels are considered. The short description of these approaches and their feature, advantages and shortcomings for practical application is given. To calculation of a drain of the Syr-Darya River in Kyzylord it is applied the method of creation of winter curves of Q = f(H). It was carried out as follows: all expenses shared on two groups ? mashing or ice dam (expenses at broken or very thin ice) and normal (at the established ice cover). Such differentiation of curve expenses specifies dependences of Q = f (H) for the second half of winter.
